Artrodesis pedicular 360º

Artrodesis pedicular 360º



360º circumferential arthrodesis with artificial disc and pedicle screws to achieve long-lasting stabilization in columns with significant instability.
On many occasions for spondylolisthesis in advanced degrees, spondylosis, scoliosis and many other pathologies the use of screws is necessary. However, traditional arthrodesis work very well when associated with discs as a very solid assembly remains. The great failure of spinal surgery that is also the generator of many erroneous myths in this pathology is the placement of screws and bars only without associating it with discs, because they only stabilize 180º and we know from statistics that between 30 and 40% of these surgeries will fail and patients may continue with the same or more symptoms as before the surgery. For this reason, as far as possible, it is necessary to seek mini-invasive surgeries with the placement of discs through the lateral or abdominal route. Or a hybrid and screwless dynamic stabilization. And when it is necessary to place screws always associated with a disk.

What is an arthrodesis?

When we speak of arthrodesis, we refer to fixing various segments of the spinal column, for this, pedicle screws associated with bars that can adopt the shape of the spine are used.

When is an arthrodesis recommended?

Screw arthrodesis is usually necessary in conditions such as spondylolisthesis, spondylosis, and scoliosis. In general, it is necessary when there are significant instabilities in some segments of the spine.


They can also work in degenerative disc diseases, provided they are accompanied by an intersomatic disc.

Why can an arthrodesis fail?

It is the most common problem in spinal surgery.



The placement of screws without discs does not work correctly in approximately 40% of cases, because, on the one hand, by blocking that segment a lot, it sends a lot of work to the adjacent discs and, on the other, because the screws either break too often, or they create slack and micromotion within the vertebrae. can be very painful.

Will I lose mobility after arthrodesis?

Patients fear losing mobility in their spine after arthrodesis, although this is not truly the case. 90% of the work of bending over is done by the hips. For this reason, before surgery with arthrodesis, the risks are more the slack caused by the screws and the workload at adjacent levels. That is why we never tire of repeating that an arthrodesis indicated to the right patient after a good diagnosis is a good solution as long as an interbody cage or disc is placed.
